The end-T of the latchbar 6. is vp iv'otally secured'tc the deer by: means [0i an angulerly inclined lug 19 which extends1 f rol -1 theendv 7 intermediately of; its length and piyctally,

Upon the bolt 15 and between the latch bar-6 and bracket 5 -,I furnish a convex, faced washer 16 so that the latch bar 6 mayreadily oscillate upon the bracket 5.

In the vicinity of the centre of the lower face of the door frame member. 9 I position a downwardly extending keeper plate 17 which is suitably secured. to the member 9; it being understood that the doors, contact with the side 18 of the member 9 so that the plate 17 does not in any way interferewith the'shutting'of the doors. This plate 17 is formed with a centrally positioned upward- 1y extending slot 19, the rear portion 20 of the plate being of less depth than the front portion 21; The portions 20 and 21 have sloped edges 22 as illustrated in Fig. 6 so that the upper edges 23 of the members 7' and 8 slide thereon into the slot 19 when the doors are swung fully open or shut as shall v be hereinafter explained.

. In the vicinity of the center of the outer vertical edge 24 of the door 21 pivotally mount a horizontal lever 25 having a handle 26' formed upon its outer end, the lever being recessed into the edge of the door so that it does not come into contact withthe edge 27 of the door 3 preventing the doors fullyclosing. The inner end of the lever 25 is connectedby'means of a chain 28 to the outer extremity of the end 7 of the latch bar 6.

secured to the outer uppercorner of its inner face, and 30 is a bar pivotally connected to the bracket 29 and extending into pivotal connection with the outer end of the bracket 5, a pin 2 or bolt 31 extending through orifices in the V vided with a plurality of boltor pin receiving bar 30 and bracket 5 to form tlie pivotal connection. The inner end of the bar 30 is proorificesl whereby the opening of the door 3 may be adjusted when my mechanism is being installed. I The operation of my invention is as follows When the'garage doors are closed the mechanism is in the position illustrated in dotted lines in Fig. 2 wherein the edge 23 of the outer end .7 of the latch bar is contained in the slot 19 in keeper plate 17 thus retaining the doors and mechanism from swinging outwardly." The "respective lengths bracket5 andbar 3O areso arranged that the door 3 completely closes in swinging the of the bracket and bar rearwardly. When it is desired to open the doors the handle 26 is grasped and moved upwardly thus pulling the chain 28 and oscillating the latch bar 6 to 'swing its end 7 downwardly out of engagement with the slot in the keeper plate 17 which permits the door 2 to be swung outwardly. When the bracket 5 swings from the position illustrated in dotted lines into the position illustrated in full lines in Fig.2 the bar 30 will be swung from the position illustrated in dotted lines into the position illustrated in full lines thus openingthe door 3 at the same time.

As the latch bar 6 is carried by the door 2 and bracket 5, the latch bar will also swing outwardlyfrom the position illustrated in dotted lines into the position illustrated in 7 full lines wherein its inner bent end will 7 engage the edge 22 of the plate 17 as the doors approach their fully open position.

As herein'before explained the latch bar 6 is loosely'mounted upon the bracket 5 and pivotally secured to the door 2 so that it is capable of an oscillating movement'permit- .ting the bent ends? and 8-t oswing downwardly in unison as lndlcated by the arrows inFig.3.

It will be therefore appreciatedthat when the edge 23 of the end 8 comes into contact with the sloped edge 22 of the plate 17 that such end 8 will swing downwardly and travel along the plate edge 22 until it reaches the upwardly extending slot 19 when its edge 23 will move upwardly into the slot as the bar 6 restores itselfto its normal position under the force of gravity; it being understood upon reference to'Fig. 2 that the major portion of the bar 6 is' lifted up whenits ends 7 and 8 are depressed and'as the weight of'such lifted portion of the bar 6 is greaterthan the combined weight'of the depressed ends that the 'The door 3 is furnished with a bracket 29 be utilized, such spring extending downwardly from the bar 6 to the doorj2.

lVhen the end 8 of the bar 6 enters the slot 19 in the plate 17 the bar 6 is of course retained against further movement in either direction which therefore locks the door 2 in the open position, and as the door 3 is connected to the bracket 5 by means of the bar 30 it will also beheld'in the open position.

WV hen it is desired to close thedoors the outer end 'of the lever 25 is swung upwardly by means of the handle 26 so that its inner end moves downwardly pulling the chain'28 and swinging thelatch bar ends 7 and 8 downwardly which moves the edge 23 of-the end and the doors closed.

From the foregoing description it will be iii) anism for double doors," a latch bar solely supported by one door and oscillatable substantially 'about its longitudinal axis, a latch bar supporting member extending from said door a bar forming a pivotal connection be tween the other door and the latch bar supporting member, and a keeper plate secured to the upper portion of the doorway, and means uponv the'inner end of the latch bar detachably engaging the keeper plate.
